Slack is simple and effective for daily team communication
Sep 17, 2025
What do you like best?
I like that Slack keeps conversations structured in channels, makes file sharing simple, and allows easy integration with tools like Google Drive and Trello. It really reduces email clutter and helps the team stay connected and efficient.
What do you dislike?
Sometimes the constant stream of notifications is distracting, so I often have to adjust settings or use “Do Not Disturb.” Also, the search function could be improved, as finding older files or messages is not always smooth.
Great tool for remote teams to stay in communication
Sep 27, 2022
What do you like best?
It is a very simple team communication tool, and the ability to create multiple group chats to enable teams to communicate about certain departments or ongoing projects. The search function also makes it very easy to find previous chats and documents.
What do you dislike?
Some of its more advanced features (beyond the basic chat functionality) require a bit of learning - and can cause problems with team members who are not as tech-savvy.
Slack enables communication & contributes to our success
Nov 4, 2020
What do you like best?
You can customize notifications, create custom channels, and integrates perfectly with all the other apps that we are using on a daily basis.
What do you dislike?
I really dislike the fact that I need to pay for a premium account in order to view past messages. However, I later found out that you would need to star important messages in order to be able to retrieve them later on.
